But one feature unique to the Mac build is support for Apple's multi-touch trackpad which has been shipping in notebooks since January of this year. While Apple's Safari supports multi-touch gestures for common web browsing tasks (back, forward, resize text), support had been absent from Firefox. Experimental Firefox support for the multi-touch trackpad was first introduced in a pre-Beta build back in October by Mozilla's Edward Lee. The changes have since made it into the official Beta 2 released on Monday and is expected to be released with the final 3.1 version of Firefox.
Supported gestures are even more robust than Safari's support and include ("Swipe" refers to 3-finger Swipe):

- Swipe Left: Go back in history (hold Cmd to open it in a tab)- Swipe Right: Go forward in history- Swipe Up: Go to the top of the page- Swipe Down: Go to the end of the page- Pinch Together: Zoom out- Pinch Apart: Zoom in- Twist Right: Next tab- Twist Left: Previous tab

Mozilla warns that the beta version of Firefox is intended for testing use only. There's no known release date for the final release of Firefox 3.1.

yeah it should be swipe to change tabs and turn for history... i use tabs a LOT more...

Agreed, which is why I was sort of shocked when I saw the set-up they had decided on.
I rarely change between history anyway, and when I want to go back I just hit backspace.

Another issue people may want to be aware of is that sometimes the trackpad can get confused. At the moment, using multiclutch at least, I only set up swipe left and right. The others can sometimes get misinterpreted.
